cargo login

Save an API token from the registry locally. The token is used to authenticate to a package registry. You can remove it using cargo logout. More information: https://doc.rust-lang.org/cargo/commands/cargo-login.html.

• Add an API token to the local credential storage (located in $CARGO_HOME/credentials.toml):

cargo login

• Specify the name of the registry to use (registry names can be defined in the config - the default is https://crates.io):

cargo login --registry {{name}}
